Title: Silicon on diamond microelectronic devices
Inventor: KRAMADHATI RAVI
IPC: H01L21/762
Filed: 2004-06-09
Abstract: A silicon device layer 222 having tensile strain is formed on a diamond 205 coated silicon wafer 202. The compressive stress induced in the silicon wafer by the diamond layer is modified by introducing defects 214 by polishing the back surface of the wafer and/or by counteracting the compressive stress by deposition of tensile polysilicon layers 220, 220' on the wafer. Reducing the compressive stress of the substrate reduces the bow and improves the planarity of the wafer. The diamond layer improves heat dissipation from the strained active layer.

Title: An apparatus and method for adjusting the focus of a digital image
Inventor: KOH SUNG-SHIK
IPC: G03B13/36
Filed: 2009-06-04
Abstract: An apparatus and method for adjusting focus using the modulation transfer function (MTF) characteristics of a lens in a digital image processing apparatus adjusts focus using optical characteristics of a lens. The apparatus for adjusting focus includes an image pickup unit in which modulation transfer function (MTF) data 507, which can be used to represent the performance of a lens, is stored; and a digital signal processing unit that calculates a focus peak value 515 of an image and a defocus correction value based on the MTF data 517, and corrects the focus position using the focus peak value and the defocus correction value 519. The MTF may be read when the image pick up unit is initialized. The defocus value may be calculated differently depending on the lens position, the type of lens (eg a zoom lens), the pixel number of an image sensor, the display condition of a live view image, and the movement amount/speed of a focus motor. Further disclosed is a method and apparatus wherein the focus position is corrected based on a stored focus correction value and an autofocus peak value (see figure 6 not shown).

Title: Method of manufacturing an electron tube
IPC: H01J19/46
Filed: 1962-03-15
Abstract: 984,577. Thermionic valves. RADIO CORPORATION OF AMERICA. March 15, 1962 [April 10, 1961], No. 10061/62. Heading H1D. During manufacture of a double-ended electron tube, the tube envelope is positioned in a jig provided with spacer members which project into the envelope through an end opening therein and which position the tube electrodes and their supports in precise relationship with each other. The electrodes and their supports are then bonded together and to the envelope before removal of the spaced members. In the grounded grid triode shown in Fig. 1, the anode and grid are supported by annular discs 58, 62, which have their peripheral edges bonded to envelope portions 12, 16, while the cathode is mounted on a flange 70 secured to three terminal pins 30. In the grounded-screen grid tetrode shown in Fig. 3, only the screen grid 149 is supported by an annular disc 162. During manufacture, the tube components, except for the cathode cup, are assembled in a jig 175 provided with a central post and four coaxial cylinders which accurately determine the axial and radial positions of the electrodes. Prior to assembly, the steel electrode supports and the metallized ceramic envelope portions are coated with copper brazing material, the jig being of an alloy which is non-wettable by copper. Rings of brazing material may also be provided round the terminal pins 30 and the ceramic wafer 122. After brazing in a hydrogen furnace, the tube is removed from the jig and the cathode cup 52, Fig. 1, is slid over sleeve 51. The tube is exhausted through opening 40 which is then closed by a disc or cup 42 sealed to flange 39 by a nickel-gold alloy. The envelope members 34, 16 are of a nickel-steel alloy and have indexing lugs 24, 25. The inductance of the electrodes is low due to the use of large area terminals, also the capacitance between anode and control grid is low due to the large spacing between their supports.

Title: Control circuit for electrical converters
IPC: H02M1/04
Filed: 1963-03-14
Abstract: 1,030,233. Phase changing. ALLMANNA SVENSKA ELEKTRISKA A.B. March 14, 1963 [March 17, 1962], No. 10084/63. Heading H2F. A phase-shifting circuit for controlling electrical converters comprises a bridge of two inductive or resistive arms, such as the two halves of the secondary winding 3 of a transformer 1, a reactive arm 4 and an arm including a current limiting member. In the arrangement of Fig. 2 the current limiting member comprises a bridge of diodes 7 and a transistor 8 whose base current Is determines the maximum current I circulating in the phase shifting bridge. In another embodiment (Fig. 5, not shown) the diode bridge and transistor is replaced by two transistors connected in series in opposite senses but controlled together. The transistor 8 (Fig. 2) may be protected against over-voltages (Fig. 6, not shown). Fig. 3 shows the voltages e 1 , e 2  at the ends of the secondary winding 3, and the current I in the phase shifting bridge which rises at a rate determined by the inductance 4 to a maximum value determined by the transistor. While the current I is rising the voltage across the transistor is small, so that the output voltage Es follows e 2 . When the transistor saturates the voltage across the inductance becomes zero, as the current is then constant, and Es then follows e 1 , so that there is a steep wave front in the output voltage. The height of this wave front depends on the value of I (Fig. 4, not shown). The circuit may control a converter valve directly or through a bi-stable circuit, and a polyphase converter may be controlled by a number of circuits according to the invention, each circuit sharing a common current limiting transistor (Fig. 7, not shown).
